Hangouts is not end-to-end encrypted and is part of a suite of products by Google, whose business model is to harvest people's personal data for profit. That makes it much less secure or private than signal. If it's video you want, try Wire or Jitsi Meet. Free, open source, encrypted, private and un-Googled.JohnFastman • 19 hours agoDisagree Agree

WhatsApp is not Free Software and is not focused on privacy. Difficult to use in Usecases which demand high control of the Software and a verifiable Data-protectionarndtadler • 13 days agoDisagree Agree

When I think of Signal, it's more of an encrypted messaging app. Facebook messenger is not privacy-oriented in any way (though it is also a messaging app.)crazypens30 • Oct 2016

Facebook Messenger is a privacy-disrespecting app. I gathers as much data about users as possible so that Facebook can sell it to advertisers. That's a disgrace. The whole point of Signal is that it's not based on a business model that violates user privacy. Signal is end-to-end encrypted and gathers as little info about users as possible. Signal is hugely preferable. It's also open source (more trustworthy; you can check what it's designed to do).JohnFastman • 19 hours agoDisagree Agree

User keys are not generated by an algorithm, but by the user.
You don't need to register a phone number or an email. A pin will be given to you and that will be enough to connect. aljasser • Mar 2017

I love Signal because of the automatic end-to-end encryption. Even though Whatsapp now has that, too, I still prefer Signal because it's more transparent about key handling. I would love them to add...
